[3] According to Sa'ad al-Ash'ari, whose account is confirmed by other sources including various narrations by Kashshi, Abu al-Khattab initially claimed that the Shi'i Imam Ja'far al-Sadiq made him his guardian and taught him al-Ism al-A'zam (the great divine name).
In a narration given by Ibn Babawayh in his work al-Khasal, citing al-Sadiq's interpretation of verses 221 and 222 of the Quran chapter Surah Al-Shaara, Abu al-Khattab is considered one of those Satan descends upon them.
[3] It seems that Abu al-Khattabb formed the Ismaili teaching about transference of spiritual authority and the Nusayris' belief in the manifestation of divinity in man (Arabic: ḥulūl).
he stated that Imam Ja’far has delegated his authority by appointing him as his waṣī (deputy or executor of his will) and entrusting him with the 'Greatest Name' of God (al-Ism al-A'zam), which was supposed "to empower its possessor with extraordinary strength in conceiving hidden matters".
Some people have said that Abu al-Khattab and his companions in Kufa, while wearing Ihram clothing, chanted the name of Ja'far al-Sadiq and testified to his divinity, which caused their murder to be accepted by the government.
Others have also mentioned that Abu al-Khattab set up a tent in the Kanasa area of Kufa and called upon his followers to worship al-Sadiq there.
